Hi,
Having a problem with sink and wondering if any one can help. The problem is i want revieve notifications back from a COM object (Netmeeting SDK INmCall and INmCallNotify). I assumed it would be a case of overriding INmCallNotify and replacing how it handles callbacks with how i want it to handle call backs, however this doesnt seem to be the case.
Can any one offer any light on the subject please, i have read a post about this but still am a little unsure.

Can you be more specific? Perhaps post some of your code.

I am tryng to create a C# application that will load a plugin that implements the following interface:
public interface IPlugin
{
bool OnMessage(IMessage Message);
}
I am trying to create a language independent plugin.
What do I have to do?
How do you create a type library for this interface?
I am not sure how to go about this.

I known app that use Com.
I want to spy it. How i do??
Because i don't know much about com. Dont laugh at me!!!
Another question: I always see examples about com like this
class obj{
class XI1: public interface1{
//code here
} m_x1;
..............
};
So, If my app want to use as many interface1 as i want.
How i write my com object.
Thanks

The only real way to see what's going on with an existing application that uses COM is to somehow implement a proxy object that can sit between the two existing objects. That's not at all straightforward, but I did do it once to try to understand what was going on with Pocket PC's Soft Input Panel input methods, so I could write one of my own.
The example you've illustrated is the 'nested classes' pattern of implementation. Here, every COM interface is implemented as its own function. The advantage of this style is that functions with the same name and parameters from different interfaces can be implemented differently, if required. MFC uses this pattern.
The other main pattern is the 'multiple inheritance' pattern, where your class derives from all of the interfaces. ATL uses this pattern. This style has a lot less 'glue' required. Personally I prefer it.
I'd recommend that if you're just beginning with COM, you should obtain the book "Inside COM" by Dale Rogerson (sadly, out of print).

Hey, Thank for your help. But i can't find myself "Inside com" or similar things. I'm very happy if you send me some of your book :->!!!

I have a simple component. It receives and stores data. The data needs to be decoded before can be used. Then I set a CodecManager in the component. When I try to retrieve the data in a event processing, the codec manager should provide a codec for use. But at this point, CodecManager failed. I don't know why? Anybody help. Is it legal to call CoCreateInstance in event processing?

U can call CoCreateinstance in the event handler but it is better u create the component some where else say add an Init function and within this u create it and use in the thread.

The information u given is too abstract. provide more clarity on ur problem or place some piece of code for reference. becaz we cant find out the root cause without code samples.

When you say 'event processing', do you mean in a COM sink interface, or normal message handling?
What HRESULT does CoCreateInstance return?
Can you write a minimal COM client that calls CoInitialize(), and successfully CoCreateInstance the codec, then release it and call CoUninitialize()?

I'm trying to make Outlook addin that will add one button to outlook context menu---
(VB.net / C# .net (NO C++ .net))
first,
ActiveExplorerCBars = applicationObject.ActiveExplorer.CommandBars
then
cmdbar = ActiveExplorerCBars.Item("Context Menu") 'cmdbar is commandbar object "^getting error here"
control = cmdbar.Controls.Add(MsoControlType.msoControlButton)
With control
.Caption = "kedar"
.visible = true
..... other props
End With
but i'm gettin an error that the parameter "Context Menu" is incorrect @ cmdbar = Active......
"i have seen code working in vb but not in vb.net so keep that in mind and reply for vb.net"
i've refered -- http://www.outlookcode.com/codedetail.aspx?id=526
http://www.outlookcode.com/codedetail.aspx?id=314 ?
and similar codes but they'r not of any use to me,.....
I think "Context Menu" is not a valid parameter. But accordg to other resources i've cometo know that outlook has that Named menu.
I'd like if anyone can post a code to add the button to context menu.
thnx in advance

HAI,
I want to know whether its possible to access a substorage directly from the root storage.
For eg.
LPSTORAGE pStorage;//Main storage
LPSTORAGE pSubStorage;//Substorage
//StgOpenstorage(...);
hr = pStorage->OpenStorage(L"abc\\13\\456",........., (&pSubStorage));
Thank you

that OCX is developed by VB6.
i can import it into CB6 through 'import ActiveX control'
but the .cpp file is empty. that mean its not included any class declear.
how can i use a VB-OCX normaly in cb6?????????????????????????

If you haven't change anything the control should end up in ActiveX-palette. Use it as you would use a normal VCL.

Hi there,
I've been developing a virtual web-cam DirectShow filter. I'd like to load a video file and transmit
it as if it comes from a WebCam.
At first I used the ISampleGrabber interface and tried to pass on the buffers I received from it.
Unfortunately, I had some wierd problems that the window that was supposed to receive the bitmaps
sometimes didn't get WM_PAINT messages fast enough and only once in a while. In other times it seemed
to be okay.
However, I decided to try something else: I built a filter graph and removed the Video Renderer filter. Then I saved the output pin to the Video Renderer filter (before removing it) and delegated
the IPin functions to that pin.
The problem is that when I use GraphEdit to connect a renderer to my filter, after the connection
both filters disappear from the filter graph. I know it has something to do with the connection of
the pins.
Is it possible to connect two pins from different filter graphs?
Is there maybe another way to do it?
I'd immensely appreciate any help!
Thanks.
